SPAN-A (pronounced 'spanner') is a candidate for the pre-midcom SPAN
protocol. The scope of SPAN (Simple Protocol for Augmenting NATs) is
to enable protocols involving multiple associated sessions to operate
across NATs. Such protocols typically use transport addresses to
identify associated sessions. This works well for environments where
end-to-end addressing is in force, but is broken by the introduction
of NATs. SPAN is intended to operate with symmetric NATs by using a
relay outside the NAT. It complements STUN [STUN] which operates
with various kinds of cone NAT.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
